CASTING-MACHINE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed March l 1906- Serial No. 303,624.

To all whom 'it may concern:

Be it known that I, THOMAS Horn CHURCHILL, of the city of Toronto, inthe county of York and Province of Ontario, Canada, have inventedcertain new and useful Improvements in Casting-Machines; and I herebydeclare that the following is a full, clear, and exact description ofthe same.

This invention relates to a casting machine comprising two separablegroups of mold members, means for accurately maintaining the moldmembers of one group relatively to the mold members of the other group,so that they will register in pairs when assembled and for collectivelyseparating and bringing the mold members together, and an adjustablemeans for revolubly holding the groups of mold members when assembled ineither a horizontal or a perpendicular position, as hereinafterdescribed and specifically pointed out in the appended claims.

For a full understanding of the invention reference is to be had to thefollowing description and to the accompanying drawings in which Figure lis a perspective view of a casting machine, with the mold memberspositioned to receive the rails and fillings. Fig. 2 is a perspectiveview of the same machine shown in Fig. 1, with the molds in a verticalposition and the groups of mold members closed together. Fig. 3 is aperspective view of the turn table and its hinge members for the moldsshown in Figs. 1 and 2, but on a larger scale than in the precedingviews and in the same position as in Fig. 2. Fig. 4 is a section of theturn table and its hinge members on the same scale as in Fig. 3 andshowing them in the same position as in Fig. 1. Figs. 5 and 5 areperspective views of two separated mold members. Fig. 6 is a view ofpart of the head or foot of a bedstead. Fig. 7 is a side view showingthe cast joint of a rail and filling. Fig. 8 is an end view of theconstruction shown in Fig. 7. I

Like letters of reference refer to like parts throughout thespecification and drawings.

The casting machine illustrated in the accompanying drawings ishereinafter described in connection with the manufacture of metal bedsand cribs, and the following description will be read with that purposein view, but it can also be used for casting other articles of like nature, and is so arranged that it can be operated by inexperienced laborof ordinary intelligence to produce the finished product.

The group of mold members a are selectively arranged on and fastened toa rigid mold frame I) and the mold frame I) is revolubly connected to ahinge member (1. Hinged to one side of the mold frame b is acorresponding mold frame e and fastened to the mold frame e are moldmembers f positioned to register with the mold members a when the moldmembers are closed together.

The mold members a and f as shown in Figs. 5 and 5", are formed withmatrices for the rails and fillings of the bed shown in Fig. 6, and whenthe mold members a and f are assembled, they constitute the molds forcasting the joints of the rails h and fillings i shown in Figs. 7 and 8.The matrices j for the rails h are arranged, in the mold members,lengthwise of the frames b and e and the matrices is for the fillings iare arranged at right angles to the length of the frames and extend fromthe matrices j to the inner sides of the molds. At the junction of thematrices j and k are matrices Z for the eyes Z of the fillings.

In assembling the parts for the construction shown in Fig. 6, thefillings i are placed in the matrices k with the eyes Z contained in thematrices Z and the rails h inserted through the eyes Z and contained inthe matrices j. and the groups of mold members are securely locked intheirclosed position to retain the rails and fillings in their relativeplaces in the molds.

Formed through the molds to the matrices Z are ingates m through whichthe molten metal is introduced into the matrices, the ingates andmatrices beingso formed as to direct the metal to the sides of the eyesZ and around the rails.

The mold members a for forming the cast joints of those structurescomprising two rails and fillings with eyes for each rail are arrangedin two separated groups on the mold frame I) and so positioned thereonthat they will hold the fillings at right angles to the rails during thecasting of the joints, and the mold members f are arranged incorresponding groups on the mold frame 6 so that they will register withthe mold members a. When the mold frame e is raised into the positionshown in Fig. 1, it will lift the mold members f collectively away fromthe mold members a and when it is moved into the position shown in Fig.2, it will bring the mold members f collectively into position toregister with the mold members a. In the operation of this part of theapparatus, the mold frame e ismoved into the position shown in Fig. 1,and the parts to be joined, viz., rails and fillings, are placed inposition in the matrices of the mold members a. This arranges all thefillings at right angles to the rails and spaces them at their selectivedistances from each other. When this part of the operation is completedthe mold frame 6 is lowered towards the mold frame I) to bring the moldmembers f collectively into position with the mold members a, and thetwo mold frames are then looked together by suitable fastening means 0.The mold members a while the rails and fillings are being positioned,lie in a horizontal plane in which it would be impracticable to pour.the molten metal into the molds when the mold members are closedtogether The mold members are then closed together and it is thereforenecessary to so arrange the apparatus that the molds can be turned fromthe horizontal .position shown in Fig. 1 to the vertical position shownin Fig. 2, and this is'accomplished by providing the mold frame I) witha turn table 0 pivotally connected to a hinge member d andarticulatingly connecting the hinge member 01 to a hinge member 1;fastened to or forming part of the machine frame q and at one endthereof. When the molds are in the horizontal posi tion shown in Fig. lor moved into the vertical position shown in Fig. 2, they can freelyrevolve collectively tact with the machine frame.

into the position occupied-by those first mentioned,

so that the molten metal can be poured through' the:

ingates m into the matrices of the second row of molds.

By the use of this apparatus it is possiblefor ineXperienced labor tojoin the rails and fillingsof the sides and ends of a crib or the headand foot of a. bedstead quickly and withoutany reasonable possibility ofmaking a mistake in the joining operation.

The above described construction is designed for the manufacture of thatclass of bedsteads andcribs in which both ends of the fillings are to bejoined to the rails.

' Having thus fully described my inventionwhat I claim as new and desireto secure byLetters Patent is;

1. A casting machine comprisinga set of molds consisting of two groupsof separablemold members, means for maintaining the groups of moldmembers relatively to each other, and for collectively separating andbringing them together; means for moving the molds into horizontaltherebyto register with the first mentioned mold members,

means for revolubly holding said frames and molds and other meansto'permit said frames and molds to collectively move into a vertical ora horizontal positionl 3. A casting -machine comprising two separablegroups wof mold members, means for accurately maintaining the moldmembers of one group relatively to the mold members of the other group,so that theywill registerin'pairs when' assembled and'for collectivelyseparating and bringing the mold members together, and means forrevolubly holding the groups of mold members when assembled in either ahorizontal or a vertical position.

4; A castingmachine'comprising'a setof m0lds,a sup porting means forthe-molds movablefromahorizontal to a vertical plane, and means forrevolubly connecting the molds to the supporting means.
